We have been discussing bone and artery health with Leon Schurgers, Ph.D. In June, we discussed why vitamin K2 was essential for bone health and in July, we examined why vitamin K2 is also essential for healthy arteries. Both involve keeping calcium in the bones and out of the arteries. Even Time magazine is now reporting that calcified arteries are a major risk factor in heart disease. New research indicates that there is more to the vitamin K2 story. Let’s continue our chat with Dr. Schurgers with a discussion about vitamin K2’s role in brain health.

Last month, Leon Schurgers. Ph.D., discussed with us why vitamin K2 was essential for bone health. To the surprise of many, studies continue to show that vitamin K2 is also essential for healthy arteries. Even Time magazine is now reporting that calcified arteries are a major risk factor in heart disease. What is the connection? Let’s discuss it with Dr. Schurgers.
